einem NURSING BOTTLE.

Application led October 21, 1921. Serial No. 509,402.

To all whom t may concern.' Be it known that I, ALONZO L. MoeLEY, acitizen of the United States, residing at Soquel, in the county of SantaCruz and State of California, have invented certain new and usefulImprovements in a Nursing Bottle; and I do hereby declare the followingto be a full, clear, and exactpdescription of the invention, such aswill enable Yothers skilled in the art to which it appertains to makeand use the same.

Nursing bottles are generally made o glass and are formed with angularportions within and without and asa consequence they are fragile,diiicult to clean and frequently injure the infant'.

The present invention provides an indestructible bottle which may beeasily cleaned and is not liable to injure the infant be 2e cause it isfree from corners and angular portions. v

The invention also provides a nursing bottle which is readily accessiblefor cleaning, which permits of the use of either the breast nipple orthe ordinary nipple as desired. l

Other objects and advantages will be apparent and suggest themselves asthe nature of the invention is understood.

ment of the invention it is to be understood that in adapting thesameyto meet dierent conditions and requirements various changes in theform, proportion and minor details of construction may be resorted towithout departing from the nature of the invention'.

Referring to the accompanying drawing forming a part of thespecification,

Figure 1 is an elevation of a nursing bottle embodying the inventionshowing the same adapted for receiving the usual small nipple. Y

Figure 2 is a sectional detail, the lower portion of the bottle beingomitted, and

Figure 3 is a detail view showing the bottle adapted for use inconnection with the breast nipple. v

Corresponding and like parts arereferred to in the following descriptionand designated in the several views of the drawing by like referencecharacters.

A nursing bottle constructed in accordance with my invention ispractically indestructible and free from corners or angular projectingparts and is of sectional formation to admit of either type of nipplebeing lVhile the drawing illustrates an embodi-A used` therewith asindicated most clearly Figures 1 and 3 of the accompanying drawing.4While any material that will withstand hard usage and heat and coldmaybe empioyed, it isl preferred to construct the bottle ofalu-minum whichis light'and not l affected by liquid contentsand .capable ofwithstanding hard usage and sudden changes in temperature. The bottleVis of sectional formation and comprises a body portion 1 and a neckportion 2. The parts 1 and 2 are preferably connected bymeans ofva'screw threadjoint which has inner and outer abutting shoulderstoprevent leakage. 'llhe juncture of the side walls with the bot-V tomisrounding as indicated at 3 and "4 thereby obviating inner angularcornersv and outer angular projections with the-result that .the bottlemay be readily cleaned and is not liableto injure the infant. The

body is provided atits mouth with an outer y beam 5 for reinforcing andstrengthening purposes and also to provide for positivev engagement ofthe breast nipple 6 as indicated in Figure 3. The body 1 is threaded fora short distance upon its interior as indicated at 7 and makesscrewthread engagement with the neck portion 2. The inner threaded portion 7is located adjacent the mouth of the body 1 and the latter is stiffenedupon its inner wall as indicated at 8 to further reinforce andstrengthen the bottle as well as to provide an inner shoulder 9 to abutthe threaded end of the part 2. The inner lower portion of the stiffenedpart 8 vanishes into the inner wall of the body l to prevent theformation of any projecting part which would tend to collect matter andrender it diiiicult to clean the bottle.

The neck portion 2 is made tapering and has an outer bead 10 at itssmaller end to provide a inish to reinforce and strengthenk the mouth ofthe part 2 and to provide positive means for attachment of the ordinarysmall nipple 11 as indicated in Figure 1. The coupling end of the part 2is externally threaded as indicated at k12 to make screw threadengagement with the part 7 of theA body 1. YThe threaded portion 12 isreduced leaving an outer shoulder V13 which is adapted to abut theextremity of the body 1. Vhen the part 2 is coupled to the part 1 theouter shoulder 13 is in' contact with the outer end of the part 1 andthe inner shoulder 9 of the part 1 is in contact with the extremity ofthe part 2. These abutting joints at the ends of the threaded portioninsure a tight joint and prevent leakage.

lhen it isrequired to use the ordinary small nipple 1l the part A2 iscoupled to the part l but when it is desired to use the breast nipple 6the part 2 is disconnected from the part l and the latter has the breastnipple iitted thereto as indicated in Figure 3. The sectional formationot the bottle admits ofthe same being readilycleaned as will "be readilyunderstood. The outer surfaces of the parts l and 2 adjacent the jointsare milled, chased or otherwise roughened as indicated most clearly inFigure l to enable a firm grip to be obtained thereon when'screwingf orunscrewing the parts.

Having 'thus described the invention, what I claim is Al nursing,rvbottle comprising` body and neck portions.y the body portion having lthejuncture ot its side and -bottom wallscurved both, internally andexternally, internal screw threads adjacent the open end of the bodjTportion7 a shoulder within the body vat the inner end ot said screwthreads, external threaded to the body, the neck and bodyV ortions oitthe bottle each having` a nipple securing rbead at their outer end7 theouter end ot the neck portion beingl of .much less diameter than thebody portion whereby either a breast nipple or .an ordinary nipple maybe used, and the neck and body portions being` serrated adjacent theirpoint ,ot connection.

In testimony whereof I aix my signature in presence of two witnesses.
